Abstract (en)
[origin: EP2940778A1] A main object of the present invention is to provide a method for manufacturing a sulfide solid electrolyte that enables a sulfide solid electrolyte whose ion-conducting characteristic is easy to be improved, to be manufactured. The present invention is a method for manufacturing a sulfide solid electrolyte including loading a raw material for manufacturing a sulfide solid electrolyte which is mainly composed of a substance represented by the general formula of (100 - x)(0.75Li 2 S·0.25P 2 S 5 )·xLiI (here, 0 < x < 100), into a vessel; and amorphizing the raw material after said loading, wherein a reaction site temperature in the vessel is controlled so that x included in the general formula and the reaction site temperature y [°C] in the vessel in said amorphizing satisfy y < -2.00x + 1.79 x 10 2 .
